 ## Unreleased
 
 * The `OpenTelemetryLoggerOptions.AddOtlpExporter` extension no longer
-  automatically set `OpenTelemetryLoggerOptions.ParseStateValues` to `true`.
+  automatically sets `OpenTelemetryLoggerOptions.ParseStateValues` to `true`.
+  The OpenTelemetry SDK now automatically sets `Attributes` (aka `StateValues`)
+  for the common cases where `ParseStateValues` was previously required.
+  `ParseStateValues` can be set to `true` manually by users to enable parsing of
+  custom states which do not implement `IReadOnlyList` / `IEnumerable`
+  interfaces.

+* Updated to use the new `LogRecord.Attributes` field as `LogRecord.StateValues`

+* Obsoleted `State` and `StateValues` properties and added `Body` and
+  `Attributes` properties on `LogRecord`. Note: `LogRecord.Attributes` and
+  `LogRecord.StateValues` point to the same data. "Attributes" is what the

 * Tweaked the behavior of the `OpenTelemetryLoggerOptions.ParseStateValues`
-  flag, obsoleted `LogRecord.State` and `LogRecord.StateValues` properties, and
-  added `LogRecord.Body` and `LogRecord.Attributes` properties.
+  flag:
+
+  * `LogRecord.Attributes` (aka `LogRecord.StateValues`) are now automatically
+  included for all log messages with states implementing `IReadOnlyList` or
+  `IEnumerable`.
+
+  * `OpenTelemetryLoggerOptions.ParseStateValues` is now used to tell the SDK to
+  parse (using reflection) attributes for custom states which do not implement
+  `IReadOnlyList` or `IEnumerable`. Only top-level properties are included.
+
+  * `LogRecord.State` will only be set to the raw state object if no attributes
+  are found.
+
+  See [#4334](https://github.com/open-telemetry/opentelemetry-dotnet/pull/4334)
+  for details.
+
+* If a template (`{OriginalFormat}` attribute) cannot be found on log messages a
+  formatted message will now automatically be generated (even if
+  `OpenTelemetryLoggerOptions.IncludeFormattedMessage` is set to `false`).
